You were sleeping in your room in the Astral Express, just laying there and looking at the ceiling, you couldn't sleep, again, nothing new...you let out a huff before standing up and walking out of your room, you walked down the Astral Express halls and stopped at Dan Heng's room, you could hear faint tapping, like a keyboard or smth, was he still awake? You noticed the door was unlocked so you opened it and peaked inside, as you looked inside you could see Dan Heng on a computer working on some data, like he usually does, you were about to leave but he suddenly spoke

Dan Heng: "Can't sleep again?"

You jumped a bit by his voice, taken aback that he knew you were there
